Abstract
An improved cooling system for a turbo charged internal combustion engine is disclosed. A conduit connects a pressurizing engine air intake to the cooling system to raise the pressure in the cooling system thereby enabling an increase of the maximum temperature which coolant in the cooling system can reach. An electronically controlled valve selectively places the expansion tank in communication with the pressurizing engine air intake to maintain a desired pressure in the tank and to prevent back flow of fluid into the engine air intake.
